% Inline math \( ... \) or $ ... $, display math \[ ... \], and the AMS
% environments (align, equation, ...). The class option (11pt in main.tex)
% scales all text, math included.
\begin{frame}{Math and blocks}
  Inline math such as \( Re = \rho U D / \mu \) sits in the text; displayed
  equations get their own line:
  \[ \rho \left( \frac{\partial \mathbf{u}}{\partial t}
       + \mathbf{u} \cdot \nabla \mathbf{u} \right)
     = -\nabla p + \mu \nabla^2 \mathbf{u} \]
  \begin{align}
    m \ddot{y} + c \dot{y} + k y &= F_y(t) \\
    \omega_n &= \sqrt{k / m}
  \end{align}
  \begin{block}{A block}
    Blocks frame a key message: \cmd{begin\{block\}\{Title\}} \ldots
